Diverse teams have been proven to be better at problem-solving and decision-making for a number of reasons. First, they bring many different perspectives to the table. Second, they rely more on facts and use those facts to substantiate their positions. What is even more interesting is that, according to the Scientific American article “How Diversity Makes Us Smarter,” simply “being around people who are different from us makes more creative, diligent, and harder-working.”

One case in point is the example of jury decision-making, where fact-finding and logical decision-making are of utmost importance. A 2006 study of jury decision-making, led by social psychologist Samuel Sommers of Tufts University, showed that racially diverse groups exchanged a wider range of information during deliberation of a case than all-white groups did. The researcher also conducted mock jury trials with a group of real jurors to show the impact of diversity on jury decision-making.

Interestingly enough, it was the mere presence of diversity on the jury that made jurors consider the facts more, and they had fewer errors recalling the relevant information. The groups even became more willing to discuss the role of race case, when they hadn’t before with an all-white jury. This wasn’t the case because the diverse jury members brought new information to the group—it happened because, according to the author, the mere presence of diversity made people more open-minded and diligent. Given what we discussed on the benefits of diversity, it makes sense. People are more likely to be prepared, to be diligent, and to think logically about something if they know that they will be pushed or tested on it. And who else would push you or test you on something, if not someone who is different from you in perspective, experience, or thinking. “Diversity jolts us into cognitive action in ways that homogeneity simply does not.” So, the next time you are called for jury duty, or to serve on a board committee, or to make an important decision as part of a team, remember that one way to generate a great discussion and come up with a strong solution is to pull together a diverse team.

Critical Thinking Questions

1. If you don’t have a diverse group of people on your team, how can you ensure that you will have robust discussions and decision-making? What techniques can you use to generate conversations from different perspectives?

2. Evaluate your own team at work. Is it a diverse team? How would you rate the quality of decisions generated from that group?
